In the UK "Argentine" is the word almost always used by official bodies like the government and in BBC reports:
- Thousands of unemployed Argentines have marched to demand jobs
- The Argentine peso ended trading stable against the United States dollar
- Following a meeting with the Argentine Foreign Minister Dr Carlos Ruckauf
- Argentines have had to struggle with military dictatorship

although the occasional "Argentinian" slips in:
- an Argentinian woman living in Britain

"Argentinian" is almost certainly more frequently used in everyday speech however. ("Argentinean", BTW, is an American spelling.)

Argentina often used to be known as "the Argentine" (short for "the Argentine Republic"), but that usage is now more or less extinct.
